LOOKING MECHANISM.

Specification of Letters Patent.

Patented Jan. 3Q, 1917.

Original application filed January 19, 1914, Serial No. 813,036. Divided and this application filed October 20, 1915, Serial No. 56, 957.

To all whom it may concern:

Be it known that I, Rrcnann C. BRADLEY. a citizen of the United States, and a resident of Shreveport in the parish of Gaddo and State of Louisiana, have invented a certaiu new and useful Improvement in Looking h lechanisms of which the following is a specification.

My invention relates to locking mechanism, and is designed particularly to lock and unlock liquid dispensing apparatus.

The present invention is a division of a prior application Number 813036, filed January 19, 1914, the subject matter of the present application being disclosed in said prior application.

An object of my invention is to provide a lock capable of being operated by any of a number of keys of a similar type but of slightly different construction one from the other. with means carried by the lock for rendering any of said keys inoperative at will.

A further object of my invention is to provide a lock having mechanism for actuating a recording device in such a manner that the owner of the key may be identified subsequently to the use of the key by noting the record which has been made.

A further object of my invention is to provide a lock with which a plurality of keys may be used of the same general type but differing slightly in specific construction. with means for rendering the alteration of a key with the intention of indicating a different registration or record, extremely dillicult, owing to certain lockout devices which will be described later.

A further object of my invention is to provide a plurality of locks of the type described each being operated by a plurality of keys and all of the locks serving to actuate a common locking rod.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is a face view of a dispensing device provided with my improved lock. Fig. 2 is a section through a portion of the Renewed October 12, 1916.

Serial No. 125,344.

dispensing device and the locking mechanism. Fig. 3 is a perspective view showing a number of locks assembled for operating a common locking rod. Fig. 4 is a sectional view through the dispensing apparatus showing the lock in position. Fig. 5 is a sectional view through the lower part of the dispensing apparatus, showing the parts affected by the common locking rod. Fig. 6 is a detail section through one of the locks. Fig. '7 is a section along the line 7-7 of Fig. 6. Fig. 8 is a section along the line S-S of Fig. 6. Fig. 9 is a section along the line 99 of Fig. (3. Fig. 10 is a perspective view of the lock showing the parts thereof separated. Fig. 11 is a detail view showing the means for preventing the operation of the look.

In explaining the locking features which forms the subject of the present divisional application, I will briefly refer to the apparatus in which the locking mechanism is primarily designed to be used, in order that the operation of the lock may be better understood.

Referring now to Figs. 1 and 4:, I have shown therein a dispensing apparatus which comprises a base portion 1 above which is mounted a cylindrical casing having a lower portion 2. an upper portion 3, and an intermediate portion 4. Surrounding the casing member 3 a hinged top which I: shall donote in general by The lower portion 2 of the casing has a plurality of doors 8, 9, and 10 which are designed to be opened by the unlocking means and to be locked again by any of a number of keys. In Fig. l- I have shown. only one of these doors 10, this being suflicient to explain'the operation of the lock. The portion 3 of the casing contains the look by means of which one having an individual key may obtain access to the device. I

In Fig. l it will be seen that there are twopartitions I and 11. Disposed on the iartition 11 is a circular track having a ball race provided with balls 13 arranged to receive and support a circular member lt carried by the bottom portion 15 of a frame composed of an outer row of uprights clearly seen in Fig. 4. The members 16 and 17 are provided with openings 16 and 17 respectively, which are arranged to register with the vertical line of openings 3 in the exterior casing portion 3 when the frame is turned on the ball bearing supports, so as to bring the parts into the position shown in Fig. 2. In order to effect this turning movement of the inner frame I provide a handwheel 18 which has an integral web 18 that passes between the lower edge of the hinged casing member 5 and the upper edge of the casing member 3 when the hinged casing is in its lower position as shown in Fig. 4, the web 18 being secured to the upright 16 in the manner shown. The frame may thus be rotated. V

Carried by the frame is a series of looks like that shown in Figs. 6 to l() inclusive. Each lock consists of a cylindrical barrel 19 (see Fig. 10) having a semi-cylindrical cut-away portion 20 and being provided with a central longitudinal slot 21 which is equal in length to the'cut-away portion, as shown in Fig. 10. The cutting away of the cylindrical member 19 at 20 leaves a larger end portion 19 and a smaller end portion 19 The portion 19 contains pins of the type met with in the ordinary Yale lock. A slot 21 is made in the portion 19 and a slot 21 in the portion 19 These slots 21 and 21 are narrower than the slot 21, but the axial planes of all three slots are coincident. The end 19 is arranged to enter an opening 17 a in the member 17, while the end 19 enters the registering opening 16 in the member 16, the lock being rotatably held in these alined openings.

Arranged to slide in the slot 21 is a stop member 22 having secured to it a rod or bar 23, which isbent at 23 and again at 23 to form a portion 23 which is parallel with the main bar 23, and which extends along the axis of the barrel 19. As will be seen from Figs. 7, 8 and 9 the'bar 23 rests upon the casing 17, and is slidable therealong, as will be explained later. Disposed in a recess 24 is a rod or bar 25 like that shown in Fig. 10. This rod has an arc-shaped lug or stop member 26 at one end and a head 27 at the other, the latter bearing a series of engaging surfaces such as those shown at 27 27, 27 and 27 The rod 25 also bears a laterally extending lug 28. The rod is held normally in the position shown in Fig. 6 by means of a spring 29, which is secured to a pin 30 carried by the member 17.

Referring now particularly to Fig. 9 I have shown therein a key 31 which is adapted to enter one of the openings 3 in the outer casing 3 and to pass through into the alined slots 21, 21 and 21*. These keys are designed to be individual keys, so that the insertion of a particular key in the lock will operate mechanism to subsequently identify which key was used to operate the lock. To this end each key is provided with a shoulder 31 on its under side, which is arranged to engage the end of the bar 23 at the stop member 22. It is also provided with a shoulder 31 on its upper side which is arranged to' engage the end of the bar'25 at the lateral lug 26, as shown in Fig. 9. These shoulders 31 and 31 are designed to be placed at different distances from the shoulder 31 which engages the outer portion of the upright 16, and which limits the inward movement of the key into the lock. Both of the members 23 and 25 will be pushed inwardly'by the mere insertion of the key 31 into the lock and the distances to which these members will be pushed inwardly will depend upon the particular key which is used with this lock. Besides pushing in these two bars the key operates the pins to permit the revolution of the lock in the same manner as in the ordinary Yale lock when the cam portions 31 at the end of the key come into engagement with their corresponding pins.

It may be desirable in some cases, as for instance where a key is stolen or lost, to range the device so that the one who has the key will be unable to unlock the dispensing apparatus. To this end I arrange a bar 32 which extends above the lock, andwhich is held at its ends by means of the members 16 and 17. This bar is provided with a slot 32 and carries a series of stop members of the shape shown in Fig. 11. Each of these stop members has a lug 32 which is'arranged when the stop member is in its upper position (as shown at the right in Fig. 11) to enter the slot 32 so asto hold the stop member up out of the way of the stop member 22, but which may be easily forced downwardly into the position shown at the left of Fig. 11 so as to bring the end 32 in direct alinement with the upwardly projecting end of the stop member 22, as shown in dotted lines in Fig.

8, thus preventing the turning ofthe key.

Secured to the portion 19 of the lock and extending laterally thereof is an arm or pin 1 33 which is arranged to engage one of the laterally extending arms 34 of a bar 34 which is slidably secured to the member 17 as shown in Fig. 3. The lower end of the bar 34 terminates in a head 35, which is arranged to enter a socket 36 at the upper end of a rod 37 this socket 36 being swiveled on an arm 56. The lower end of the rod 37 is bent laterally as shown at 37 and is adapted to enter either one of a plurality of U-shaped sockets such as those shownat 38 38 and 38 in Fig. 3 carried at the upper ends of rods 39 39 and 39 respectively. As will be seen from Fig. 4, the rod 39 is bent forwardly to operate the door 10.

A detailed description of the means by which the door 10 is unlocked and again.

locked may best be had by referring to Fig. 5. In this figure it will be seen that the rod 39 is bent downwardly and passed through a guide member 40 on the inner side of the casing member 2. 'l he lower end of the rod 39 is arranged to engage a slidable member 41, which is carried by a slotted housing 43 secured to the inner side of the door 10. The member 41 has a pin 48 which enters the slot in the housing to limit the movement of the member 41. A spring 44 tends to normally keep the member 41 in the dotted line posi tion shown in Fig. 5. It will be apparent that when the cylindrical member 19 of the lock is rotated by means of the key with the rod 37 in the position shown in l? 3, the latter will be pushed downwardly and will carry with it the rod 39 so as to force the member 41 in the position shown in full lines in Fig. 5, whereupon the door 10 will be forced outwardly and downwardly into the position shown in Fig. 4 by means of a link 45 whose outer end normally rests against the door in its closed position, as shown in Fig. 5 and whose opposite end is pivotally attached at 46 to the arm 4'7 (see Fig. 4) of a. valve 48, the arm 4'? being normally under the tension of a spring 49. As will be seen from Fig. 2, the arm 47 is held in a downwardly inclined position by means of the link 45 which rests against the door. In this position the spring 49 is under tension.

As will be seen from Fig. 4, the rod 89 is provided with a catch 39 which engages underneath a lug 2 of the interior of the casing 2. A spring pressed pin 50 is carried by the casing 2 and is arranged to move outwardly when the door 10 is op ned. The engagement of the catch 39 with the lug 2 prevents the return of the rod 39 to its normal position and hence prevents the release of the key until the door is again closed. l fhen the door is swung upwardly it engages the pin 50 andforces it against the lower end of the rod 39 thus pushing the catch 39 away from its lug 2 and permitting an upward movement of the rod when the key is turned in the reverse direction so as to bring the cylindrical member 19 into its normal. position. It will thus be seen that if one should forget to close the door he could not withdraw his key. This will insure the closing of the door.

Suliicient explanation of the operation of the apparatus has already been given, so as to afford good understanding of the arrangement of the locking system. The locks are arranged in horizontal rows in a frame. Each of these horizontal rows is designated by particular serial letter. Thus in Fig. 1 the letters run from A to J. lhe locks, however, are not only arranged in horizontal rows, but they are also arranged in vertical rows, such a vertical row being shown in Fig. 3 and also in Fig. 4. Each vertical row is devoted to keys having numbers which fall between certain limits, thus the first vertical row may take keys numbered from 1 to 50, the second vertical row keys numbered from 50 to 100, the third vertical row keys numbered from 100 to and so on.

Referring to Fig. 9 it will be seen that the end the bar is arranged to engage a member on the end of a rack 6i which meshes with a gear 62 on a shaft 63 provided 2 h a number wheel 64. A spring 65 bears at one end aga est a fixed member 66 and at the other end on the member (30. l v hen the owner of the key inserts it in the lock the rack (31 will ,,be pusher forward and will therefore turn the gear 62 gular distance proportional to the distance that the rack 61 moves and this is dependent upon the movement of the bar which is engaged by the shoulder 31 of the key 31. it will be obvious that by varying the position of the shoulder 31 to correspond with the numbers on the wheel said numbers key for rendering said key inoperative.
